HOISTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 768,746, dated August30, 1904.

Original application filed April 15, 1898, Serial No. 677,727. Dividedand this application filed August 8, 1902.

Serial No. 118,897.

To @ZZ whom it may concern.-

Be it known that I, ARTEMUs N. HADLEY, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvementsin Hoisting Apparatus,of which the following is a specification.

My invention relates to an improved hoisting apparatus, and the presentapplication is a division of my application Serial No. 677,727, (PatentNo. 687,229.)

The object of my invention is to provide horse-operated means foroperating a hoisting mechanism.

The accompanying drawings illustrate my invention.

Figure 1 is a plan. Fig. 2 is a section on line 2 2 of Fig. 1. Fig. 3 isa detail. Fig. 4 is a longitudinal section justto the left of finger 2Oin Fig. 1.

In the drawings, 4 indicates the tongue of a. vehicle. Longitudinallymovable upon tongue 4 is the usual doubletree 5, said doubletree beingprovided, however, with a bolt 6, the head 7 of which runs beneath theprojecting flanges of a pair of angle-irons 8, mounted upon the tongue.Running. back from the doubletree is a pair of converging chains 9, theadjacent ends of which are secured to a shoe 10. Shoe 10 is providedwith a bolt 11, the head 12 of which runs beneath the flange of irons 8.Secured to shoe 10 is a cable 13, which runs to the hoisting-drum 14,provided with a return-spring. (Not shown.) Drum 14 is fully describedand claimed in the application above mentioned. For the purpose ofholding the doubletree against the pull of the horses I mount insuitable bearings 15 to rear of the normal position of shoe 10 arock-shaft 16, provided with a finger 17, which lies normallyimmediately in front of said shoe. Shaft 16 is provided with a suitableoperating-lever 18. In order to properly center shoe 10 and relieve bolt11 from transverse stress, the-front face of said shoe may be providedwith a pair of ears 19, between which finger 17 may lie.

(No model.)

In order to prevent the forward movement of the harvester or otherportable platform upon which the-mechanism may be mounted when the loadis being lifted, any suitable brake or lock may be used; but in orderthat its action shall be automatic I provide the locking-lever 20. Lever2O is provided near its rear end with a notch 21, arranged to receivethe projecting edge of the wheel-tire 22. Lever 20 is provided on itsunder side with a notch 23, arranged to receive a rib 24, carried by abase-plate 25. Base-plate 25 is provided 'with a pair ofupwardly-extending ears 26, be-

tween which the locking-lever is mounted. In order to prevent the lever20 from slipping in either direction, it is provided with lugs 27,arranged on each side of ears 26. The forward end of the locking-leveris passed over the rock-shaft and connected with an arm 28, carried bysaid shaft, thearrangement being such that when said shaft is rocked, soas to lift finger 17 away from shoe 10, the said locking-lever will betilted until the edges of notch 23 grip the wheel-tire, the grip uponsaid tire being sufiicient to maintain the several parts in theirunnormal position until they are forced down by the operator.

In operation the operator throws lever 18 and its shaft 16 until finger17 rises clear of shoe 10. The doubletree and shoe 10 may then beadvanced along the tongue, thus operating the hoisting-drum 14. Therocking of shaft 16 swings lever 20 and causes the edges of notch 21 togrip the traction-wheel, and thus hold the vehicle. When the load hasbeen lifted and dropped, the spring of drum 14 will draw shoe 10 anddoubletree 5 back along tongue 4 to their normal positions, and finger17 may then be thrown down in front of the shoe.

I claim as my invention- 1. In a hoisting apparatus, the combinationwith a suitable portable platform having a tongue, a horse-hitchingmeans, such as a doubletree, mounted upon and movable along said tongue,a shoe connected with said hitching means and also provided with meansto which a Cable may be secured, a rock-shaft mounted to the rear of thenormal position of said shoe, and a finger earried by said shaft inposition to be thrown in front of the normal position of the shoe.

2. In a hoisting apparatus, the combination with a suitable wheeledplatform, of a horse-bitching means mounted. thereon and provided withmeans to which a cable may be attached, means for releasing saidhitehing meehanism, and a brake or stop arranged to engage one of thewheels of said platform.

3. ln a hoisting apparatus, the combination with a suitable wheeledplatform, of h orsehitehing means mounted thereon and provided withmeans to which hoisting meehanismmay be eonneeted, means for releasingsaid hitching means, a brake orstop arranged to engage one of the wheelsof said platform, and intermediate eonneeting mechanism between saidbrake and releasing' means whereby, when the hitehing means is releasedthe brake will be thrown into engagement with the wheel.

4. 1n a hoisting apparatus, the combination with a suitable wheeledplatform having' a tongue, of a horse-hitehing means mounted upon andmovable along said tongue, a shoe connected to said means and adapted tobe connected to a hoisting-Cable, a rook-shaft, a linger carried by saidroelsshaft in position to be thrown in front of the normal position ofthe shoe, a brake mounted in position to en gage one of the wheels ofthe platform, and connections between the brake and rook-shaft for thepurpose set forth.

In witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 5th day 0f August, A. D. 1902.
